ASWITCHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 508,274, dated November 7, 1893. I Application led May 8,1893. Serial No. 473,340. (No model.)

To all whom it may con/cern,.-

Be it known that I, GIPP BREWER, of the city of Sylvia, county'of Reno,` and State of Kansas, have invented certain new and useful Y Improvements in Switching Devices, of which the following is a full, clear, and exact de` scription, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to an improvement in switching devices for street and other cars, and consists in the novel arrangement and combination of parts hereinafter" described and designated in the claims.

The objectof my invention is to provide an improved mechanism by means of v which street railway switchesv may be operated from the cars, while the operator stands upon the car platform.

In thedrawings: Figurelis a sectional' side elevation of portions of the car and rail- Way track, having my invention applied thereto. FigL'Z is a top plan View of the railway track, and switch. Fig. 3`is a detail view in perspective of the pivoted switch-tongue, and -the operative parts located adjacent thereto, detached. Fig. 4 is a sectional end elevation takenthrough one rail of a track on the line A--A'of Fig. 1. Fig. 5 is a detail top plan view of aportion of one rail, and illustrating the mannerV in which a rotary plate carried by the car. engages the switchoperating arm. Fig. 6 is a'perspective View l of a rock lever adapted to be engaged by the wheels of cars approaching the switch. Fig. 7 is a detail top plan view, with parts shown in section and broken away, taken on line B--B of Fig. l.

1 indicates the two main rails of the track, one of them connecting with a xed frog 2 of the usual construction and the other connecting with a pivoted tongue 3.`

4 indicates a slot formed in the flange of the rail which is 'connected to the switchtongue, and extending longitudinally in said flange. v

5 indicates another slot formed in said flange of said rail intermediate of the first mentioned slot and the switch-ton gue, and extending transversely with relation to said rail.

The main'operating parts of my invention "are located in an underground passage formed from invasionfof dirt and waste material.

Pivotally mounted in the passage beneath said rail is a rock lever 7.V This lever extends longitudinally in said passage and is pivoted at 8 intermediate of its length to a bracket 0rstand 9,'so that when one of its ends is de pressed 4its opposite end will be elevated a corresponding distance.`

' 10 indicates a push-head or 'arm mounted vupon the end of the lever 7 most remote from the switch -tongue, and extending upward through the slot 4 and normally projecting in the path of the flanges of the passing carwheels. The upper side of this head is preferably rounded, so as toV not present an abrupt obstruction to car wheels or other things which may come ,in contact with it.

10 is'provided with abroad tlat'surface 11,

which extends transversely a considerable distance beyond each side of said lever.

l2 indicates a Avertical arm,` the lower end of which rests loosely upon the flat plate 11 of the rock lever 7, and extends upward through the slot 5, for a purpose hereinafter. mentioned.

13 indicatesa rock-shaft, which is mounted before mentioned and extends longitudinally thereof beneath one-of said rails, so that one end is located directly above the nat plate 11 of the rock lever 7 and its opposite endis locatedbeneath the switch tongueS.

The vertical arm 12 is preferably angular in cross section, and it loosely engages an angular opening 16 formed in the projecting end of said shaft 13 above said flat plate 11. Fixed upon the end of the shaft 13 which is opposite the angular opening 16 is an eccentric disk or a cam-disk 17.

18 indicates a vertical rock shaft, the lower end of which is mounted in a bearing 19 fixed upon the bottom of the passage beneath said rail, and the upper end of which is rigidly fixed tothe end of the switchLton gue 3 whichgis opposite its point. Projecting from the verti- The end of therock-lever which is opposite the head cal rock-shaft 18, so that their inner ends are iixed to said shaft and so that their outer ends are free, are a pair of arms 20 and 21. These arms diverge so that a space is formed within their free ends, and the eccentric 17 is located in this space so as to be engaged in opposite sides by said arms.

22 indicates a car having the usual wheels 23 and platform 24.

Mounted in suitable bearings 25 and 26 upon the car platform to revolve, is a vertical shaft 27 having a suitable handle 28 upon its upper end. The lower end of this shaft projects downward to a point adjacent the rail 1 beneath which the previously described mechanism is located; and upon which end of this shaft is a plate 29 having vertical sides.

The operation is as follows: As the car 22 approaches the switch in the direction indicated by the arrow, one of its wheels 23 runs upon the head 10 which projects in its path and this head is thereupon depressed to the position indicated by dotted lines in Fig. 1, and the lever 7 is rocked upon its bearing and the dat plate 11 is moved upward a corresponding distance, carrying with it the vertical arm 12, so that the upper end of said arm projects upward through the slot 5 in the path of the plates 29 carried by the car. meanwhile, the operator upon thecar should grasp the handle 28 of the shaft 27 and set the plate 29 in such a manner that one of its sides will strike the projecting upper end of the arm 12 and form an inclined plane, and throw said arm to one side or the other; (See Fig. 4.) If the plate 29 be set at the angle shown by solid lines in Fig. 5, said arm will be thrown in one direction while if set at the angle indicated by dotted lines at the right hand of Fig. 5, said arm will be thrown in au opposite direction, while if the sides of said plate be set parallel to the rails of the track, said plate will pass by said arm 12 without moving the same from the position it occupies. If as before stated, said plate be set at an angle said arm will be thrown to one side, and the rock shaft 13 will be moved in its bearings, and the eccentric disk 17 will move with it and engage the arms 2O and 21, and throw the point of the switch tongue 3 in a proper position for the car to pass either upon the main line or the switch. After the car has passed, the preponderance of weight in the arm 12 and the adjacent end of the rock lever 7 causes In the these parts to gravitate downward and resume their normal positions, which is that shown by the solid lines in the drawings, and they are then ready for the passage of another car.

What I claim is- 1. The improved switching device, constructed with a rock-lever 7 having a head to beengaged by wheels of passing cars, a vertical arm normally located below the track out of the path of said wheels, and loosely mounted at its lower end upon the free end of said rocklever which is beneath the track, so as to be projected upward into the path of a plate adj ustable to diercnt angles upon the car, to engage said vertical arm upon either of its sides when said arm is projected upward, a rock-shaft extending longitudinally of the track below the same and having an opening 16 in which said vertical arm loosely slides, above said rock-lever, an eccentric-disk 17 on this rock-shaft, said rock-shaft being rocked by said vertical arm, after said arm has been projected upward by said rock-lever, a switchtongue, rails, and connections between said tongue and the eccentric-disk for rocking or moving said tongue when said rock-shaft is moved by said vertical-arm, substantially asV anism, constructed with a rock lever 7 having a head 10 projecting through a slot in one of the rails into the path of passing car-wheels, an arm 12 having its lower end connected to said rock-lever so that its upper end will be projected upward into the path of the plates carried by passing cars upon the depression of said head by a car-wheel, a rock-shaft 13 mounted in bearings 14 and 15 in a spacebeneath the track and having an angular opening 16 which is engaged by said arm 12, an eccentric disk 17 mounted upon said shaft, a vertical rock-shaft 18 having its lower end mounted in a bearing in said passage, a switch-tongue 3 fixed upon the upper end of this shaft 18, and a pair of arms 20 and 21 projecting from said vertical rock-shaft and engaging said eccentric disk upon opposite sides thereof, substantiallyas herein specified.

In testimony whereof I affix my signature in presence of two witnesses.
